So I'm building a new computer with the latest Haswell CPU. I want to do this right, so I'm looking to purchase a SSD and use a HDD for data and media. For the people that know more about the SSD hardware, what specs should I look when shopping for one? Some say IOPS, some say the Random 4K R/W, and some day the MAX R/W. So which is it? I've been eyeballing this one: SAMSUNG 840 Pro Series MZ-7PD256BW 2.5" 256GB SATA III MLC Internal Solid State Drive (SSD) - Newegg.com But then I just received an offer for this one, but the specs are not that great compared to the Samsung: Rakuten.com - OCZ Agility 3 480GB 2.5" SATA III Solid State Drive (SSD) Hope someone can help. Thanks.
